Great hint, thanks!I bet you are running virtualized using KVM.
Richard.
yes, correct - KVM of Opensuse 12.1 with current updates.
Can you reproduce it with KVM? Or is it a known issue with KVM?
It's a know issue with KVM and interaction with GMP. Supply a proper
CPU config to KVM - the default ones causes cpuid to spit out
impossible values (and gmp abort()s on that).
